Why use this converter

  • Your files stay with you

    Conversion runs on your device. Recordings are never uploaded, so nobody but you can hear them.

  • A WAV that opens everywhere

    Audio is saved as 16-bit PCM at the sample rate and channel count of the original MP3 — any app can open it.

  • No further loss

    The MP3 is decoded once and WAV stores it uncompressed, so editing and re-saving no longer cost quality.

  • Many files at once

    Add up to 100 files at a time and download the results as one ZIP.

Frequently asked questions

Why convert MP3 to WAV?

Video editors, audio editors, samplers and some devices need WAV or don't understand MP3. WAV stores audio uncompressed, which makes it easy to edit.

Will the quality improve?

No. The WAV reproduces the MP3 exactly, but details lost when the MP3 was made won't come back. From here on, though, editing costs no further quality.

Why is the WAV so much bigger?

WAV is uncompressed: a minute of 44.1 kHz stereo is about 10 MB. So the WAV is usually 4–11 times larger than the MP3, depending on its bitrate.

What kind of WAV do I get?

16-bit PCM with the same sample rate and channel count as the MP3 — usually 44.1 kHz stereo. Every app and device supports it.

How many files can I convert at once?

Up to 100 files per batch. Download them one by one or all together in a single ZIP file.

Is it safe?

Yes. Only the converter itself is loaded from the site; your recordings are processed in your browser and never sent to a server.
